Equipment Profile: Cobra KING OS Irons

More than two decades since Cobra came out with the original Oversize irons, the company has now introduced the KING OS Irons, and it’s sweet. Launched in 1994, the original Oversize became a bestseller and was in fact the best-selling iron in the market for two years, 1995 and 1996.

And now, the company claims to have built the largest sweet zone ever.

Today, Cobra is all about distance. The KING OS, it’s the first Cobra iron to reach the USGA’s COR (Coefficient of Restitution) limit. The KING OS is geared for the high handicappers, and is billed as a Super Game Improvement Iron.


Sweet Zone TM

A thin, high strength face construction helped create a Sweet Zone that’s on an average 12% larger than their F6 in the mid-irons, 7% larger in the long irons and 5% larger in the wedges. This means more ball speed and controlled distance.

Oversized Profile

Cobra has come out with the largest iron profile which resulted in increased Moment of Inertia (MOI) providing more forgiveness to make it easier to hit the center of the clubface more consistently. This helps to generate more ball speed on off center hits for effortless distance.

Centered CG

Using a full hollow body construction combined with Tungsten weighting, Cobra has positioned the CG lower and centered in the club head to deliver more forgiveness and precision. This perfected CG positioning produces a higher launching, more powerful feeling iron.

PWRshell Face TM

The KING OS features a thinner, stronger face and sole structure which has been re-engineered for speed. More speed translates to more distance.

100% CNC Milled Grooves

The CNC Milled grooves increases spin and optimizes trajectory throughout the set. This results in improved control and additional workability.

Progressive Spin Technology

King OS irons come equipped with V-grooves on the 4-6 irons to reduce spin, U-grooves on the 7-PW to optimize spin, and wedge-spaced grooves on the GW and SW to produce extra spin to dial in shots around the green.
